EDVARD RAU, OF ALBANY, NEWT YORK.

SHOE.

SPEGIFICATION forming part of Letters Patent No. 425,254, dated April 8,18,90.

Application filed January l0, 1890. Serial No.336,551. (No model.)

To all whom t may concern:

Be it known that I, EDWARD RAU, a citizen of the United States, residingin the city and county of Albany, State of New York, have invented a newand useful Ventilating- Shoe, of which the following is a specification.

My invention relates to improvements in hoot-s and shoes; and the objectof my invention is to provide a shoe so constructed that a ventilationwill he given thereto from the lower portion of the shoe. I attain thisobject hy means of the mechanism illustrated in the accompanyingdrawings, in Which-' Figure l is a plan showing the inner sole of theshoe. Fig. 2 is a section along the line 1 l of Fig. l. Fig. 3 is a rearelevation.

Similarletters refer to similar partsthroughout the several views.

lt is a Well-known fact that many people are troubled with profuseperspiring of the feet, especially when wearing heavy winter shoes orboots. In order to prevent this disagreeable and unhealthy occurrence, lhave provided a means for allowing a circulation of air beneath the soleof the foot. For this purpose l puncture the inner sole c of the shoe,forming a series of apertures b extending around the inner sole from thetoe to the heel. Along the outer edge of the inner sole the upper isattached in the usual manner, and a strip of leather C is secured to theinner sole around the shoe from toe to heel, and in the center of theinner sole is secured the strip G', extending` from toe to heel, leavinga narrow groove or channel c, into which the holes b open. municate withthe outer surface of the shoe hy means of the grooved strip H, attachedto the upper just above the heel, and provided with a longitudinalgroove on the side, placed I cause the channel c to conlin contact withthe upper, said groove placed in connection with the channel at theheel, the grooved strip H being bifurcated at one end and attached tothe shoe on each side of the channel. As thus arranged the air willcirculate through the opening in the heelpiece into the channel c, andfrom thence through the apertures Z9 to the interior of the shoe. Iattach the sole D and heel E in the usual manner.

As thus constructed my shoe is light and' flexible, and having the pieceC attached to the inner sole makes it unnecessary to have so heavy ashank as is usually placed in the instep of a shoe. The expense ofmaking the shoe is not augmented to any appreciable eX- tent, and thevalue of the shoe to the user is greatly increased. Perspiring of thefeet is avoided and the object for which the invention is made isattained.

What I claim as my invention, and desire to secure by Letters Patent,is-

In a shoe, a perforated inner sole havinga narrow strip of leather Cattached to its lower surface, and extending around thesole near theedge, and also having' a strip of leather C placed in thecenter of thelower surface of said sole, extending from heel to toe, forming achannelentirely around the shoe, the perforations in said inner sole openinginto the channel c between the two strips C and C', with the hifurcatedgrooved strip l-l, att-ached to the outer side of the upper just abovethe heel, the groove in said strip H communicating With the channel c,all substantially as described.
